Abstract (en)
[origin: EP1223307A2] A turbine blade has a shape such that the diameters of circles inscribed between the belly and back sides at different positions of adjacent blades decreases as one goes from the front edge to the rear edge. Since the blade has such a shape, even if the influent angle and effluent angle of gases are increased, a deceleration passage is not formed in the passage between the adjacent moving blades. <IMAGE>
